"There are psychics all over town going, 'Didn't see that coming! Hard to call,' " Weatherly joked in his trailer, while eating a slice of cold pizza. "But it's a great feeling. It's like those movies about the racehorse that's not supposed to be -- we weren't bred in some Kentucky barn of some billionaire who has Arabian stallions. We're just a plow horse. But we run fast! It's one of those stories."
To be sure, "NCIS," a spinoff of "JAG," has never been a dud. The Navy crimes procedural premiered in 2003 and finished in 26th place its first year with 11.8 million viewers. The audience grew steadily, ranking in the top 20 during seasons 3, 4, and 5 -- standing strong against the mighty "American Idol" -- until it pushed ahead to fifth place last season, encouraging CBS executives to launch a spinoff. That new series is way ahead of the pack, even surpassing the success of "The Mentalist" last season.

But as loyal as the "NCIS" fan base has been, the older-skewing series has never been a water cooler show among TV critics. Its median age is 56.6, though this season the drama also boasts a 28% boost in 18-to-49-year-old viewers, due, in part, to the success of the series in syndication on USA. "NCIS" is winning its time slot and ranks ninth among shows in that advertiser-coveted demographic this season.

"We're a very strange little show," agrees Weatherly, referring to its blend of mystery, romance, action and humor. "There's a real '80s and even '70s throwback feeling. You get a kind of 'Barney Miller' feel with it. It's not quite so grim and static and monotone and dour as a lot of crime shows."
